Description.

As seen in the drawings a nozzle when constructed in accordance with the present invention has a tubular neck 8, the extremities whereof are provided with screwthreads, the one to receive the threads of the ring 9, and the other, the circular race for the balls 11 of a friction reducing hearing. A second race 12 for the balls 11 is provided. This is held in position by the overturned flange 13 of a collar 14:. The neck 8 has a collar 15 which extends over theflange 13 to lock the neck and parts associated therewith in service position. The ball bearing thus furnished permits the neck and parts associated therewith to turn with very little friction.

The ring 9 is connected with and supports the nozzle head 16. The head 16 is approximately mushroom shaped, the body being ci.rcumferentially hollowed to form an overhanging wall 16 The head 16 has an inverted tubular spout 17 from Which the water supplied to the nozzle is delivered in an approximately forward direction by means of the passages 18.

As seen best in Fig. 3 of the drawings, the passages 18 are preferably inclined in opposite directions so that the water delivered by the spout 17 is delivered adjacent the aXis of the nozzle but in jets inclined in opposite directions, The object of the construction is to form in this manner a circular boring or washing action on any obstruction in front of the nozzle. The external wall of the Serial No. 45,498.

spout 17 is shaped so that in conjunction with the interior surface of the overhanging wall 16 it forms a substantially parabolic path for the delivery of water which strikes the wall 16 adjacent the apex of the curved surface to be gradually diverted from the forward direction and delivered in a path approximately parallel to the flow of the water through the hose pipe and neck 8 of the nozzle. This method of handling water under pressure has been found to be the most eflicient in its dynamic or propell ng action.

The ring 9 is connected with the spout 17 by a series of vanes 19. As shown best in Fig. 2 of the drawings, the vanes 19 are slightly inclined to be acted upon by the water flowing through the neck 8 to impart to the nozzle a rotary action. The rotary action thus imparted assists materially the streams of water delivered from the pa sages 18 in boring or cutting out the obstacle in advance of the nozzle.

It will be understood that while I have shown and prefer to employ two delivery passages 18, the number may be increased without varying from the scope of the pres ent invention.

In all the constructions, however, the purpose and effect would be substantially the same, to wit, to clear the obstacle in front of the nozzle so that the flow of the water therethrough when delivered backward by the overhanging wall 16 will propel or drive forward. the nozzle.

1. A. nozzle as characterized comprising a neck portion of ascertained diameter, a head having an open cup like under surface for expulsion of water rearwardly therefrom when delivered by said. neck thereto, a spout centrally located on said head and extending into said neck, the walls of said snout initiating the water in the curved path to be followed in contact with said head. said head having forward delivery passages coimnunicating with said spout, and head supporting means formed on the inner end of said spout for detachable connection with said. neck.

.2. A nozzle as characterized comprising neck portion of ascertained diameter, and a head having an open cup-like under surface for the expulsion of water therefrom when delivered by said neck thereto; means centrally located for parting; the water when delivered from said neck to initiate the Water in the curved path which it is desired to follow in contact with said head; and means supporting said head on said eek, said head supporting means embodying a plurality of inclined vanes for imparting a rotary movement to said head; and means for delivering; water from said head rdjacentthe axis thereof, said Water delivering means embocying a plurality of delivering orifices extending from the axis of said head.

3. A nozzle as characterized comprising a neck portion of ascertained diameter, and a head having an open cup-like under surface for the expulsion of Water therefrom when delivered by said neck thereto; nieai'is centrally located for parting the water when delivered from said neck to initiate the water in the curved path which it is desired to follow in contact. with said head; and means supporting said head on said 110k said head supporting means embodying a plurality of inclined vanes for imparting a rotary movement to said head; and means for delivering Water from said head jacent the axis thereof, said water tlQll'Vtii means embodying a plurality of rleljirering orifices extending from the axis of said head, said orifices being inclined in (onformity W'th said vanes to cooperate therewith in rotating said head.
